Functions can be assigned to key-operated switch positions by the
machine manufacturer. Using machine data, it is also possible to set
access to programs, data and functions to suit the user's
requirements.
The key-operated switch on the SINUMERIK 840D has 4 settings,
assigned to protection levels 4 to 7.
The key-operated switch has three different colored keys which can
be removed in the specified positions:
Switch positions
Position 0
No key
Protection level 7
Position 1
Key 1 black
Protection level 6
Position 2
Key 1 green
Protection level 5
Position 3
Key 1 red
Protection level 4
The screen is not automatically updated after a change in access
authorization (e.g., when the key-operated switch position is
changed), but only when the screen is next refreshed (e.g., on closing
and opening a directory).
The currently valid access authorization is checked every time a
function is executed.
If the PLC is in the STOP state, the input image of the machine control
panel is not scanned. For this reason, the key-operated switch
positions are not evaluated during commissioning.
